The MTA’s “Summer of Hell” may cool a bit next month — thanks to a crowd-sourced shuttle service being readied by Ford Motor Co.

Ford will launch the service by offering round trips — for $4 each way — for routes between Greenpoint and Dumbo, as well as a circuit between Midtown and the Lower East Side.

Customers will be driven by professional drivers in WiFi-outfitted Ford Transit vans that accommodate 14 passengers apiece.

Ford’s so-called Chariot shuttle will expand its service in the coming months by asking prospective customers to propose new routes on its site, http://www.chariot.com.

Ford expects that Queens and other “transit deserts” — as the company calls areas with few public-transportation alternatives — are the most likely beneficiaries of Chariot’s expansion.

Only 54 percent of Queens’ housing units are within half a mile of a subway, for example, compared with 94 percent of those in Manhattan, according to research by New York University’s Furman Center.

“We want to connect people more easily to where they want to go – whether they need help making it to a transit hub or live in an area underserved by public transportation,” said Chariot CEO Ali Vahabzadeh, who founded the service in San Francisco three years ago.

The service is also up and running in Austin and Seattle.

Ford, which acquired Chariot last year, is committed to having 60 Ford Transits operating in New York by October.

A Chariot app will display new crowd-sourced service areas, while Ford’s own data and analytics team will assist in the logistics of serving them.

The app will also allow commuters to reserve a seat and pay their fares through prepaid and tax-free accounts like WageWorks.

“We know how important it is for everyone to be able to get around effectively — especially when there’s heavy traffic,” said Jessica Robinson, the director of Ford City Solutions.

In San Francisco, where 200 Ford Transits serve 12 areas, Robinson noted that 20 percent of Chariot’s customers take the vans to connect to transit hubs such as BART, Caltrain and ferry terminals.

Founder Vahabzadeh predicted that New Yorkers will also embrace the service as a first-and-last-mile solution that eases the burden on public transportation — without costing the city a dime.

An added benefit, according to a KPMG study, is that every Chariot vehicle in operation removes ten cars from the road.
